外文摘要：Analysis of Pb+Pb data for net-charge fluctuations at LHC energies using the HYDJET++model is presented.The strongly intensive quantities D and Σ were used to remove the effects related to system volume fluc-tuations.We employed two versions of HYDJET++for the analysis.The first one is the standard or default version,whereas the second one is a modification that takes into account explicit event-by-event conservation of the electric net-charge of produced particles.The inclusion of the canonical net-charge conservation in the model allows for bet-ter description of the experimental data obtained by the ALICE and CMS Collaborations.A comparison with calcu-lations from other models is also presented.
